Why use an ear?

Hello-
I have trouble understanding the packaging of an ear. I understand that it packages an entire enterprise application, but don't you usually want to deploy EJB's in a separate container than your wars?
How would you do that with an ear?

Don't think about it in terms of containers. Just think about it in terms of the relationship between your
application components. It's very typical for web components to be packaged within the same
application as EJBs that they use. If your web components access a Local EJB interface you should
always package them in the same application as those EJBs.

Why can caller hear me when i use and ear bud

Why can't caller hear me when I use an ear bud. I am using the same ear bud that I used with the Cosmos touch. The Cosmos 3 that I just received worked for awhile with the ear bud but not it's now. Any suggestions? I'm seriously thinking about going back to my Cosmos Touch, I'm not like this 3. The only thing I like about it is the keyboard.
Thank You

clb19,
We definitely want you to enjoy the new phone as well and it's imperative to get the earbuds working with the phone. Have you tried a different set of earbuds? It it one ear bud specifically? Other than this, do all other sound options work? Is there any damage to the phone?

Why use Oracle 8.1.5 for Linux?

Dear,
If it is really pain in the ass to install Oracle on Linux, why
use it? I have spent more than 4 full days (more than what I
excepted) to try to install Oracle on a Linux box.
I guess I will go for mySQL since I can just install the RPM
package and do not have to worry those critical issues.
Just a note for Oracle, please design a better Installer next
time which is going to work! Thank you.
Best Regards,

I have some sympathy for your plight. I have 8.0.5 installed on
RedHat Linux. Apart from patching the Pro*C configuration file,
everything is fine.
It does seem 8.1.5 is more problematic. If you're purely
evaluating Oracle, maybe you should consider 8.0.5 until 8i
stabilises unless you really are gagging for some 8i feature.

Why Using Top Link is best in DB Adapter?

Hi All,
Can any one suggest , Why Using Top Link (Build-in Insert, Select etc. operation) is best in DB Adapter over using custom query?
Thanks

Hi Vikky,
for insert/select it depends on what kind of user you are. TopLink lets you browse and click on a tables and have everything generated for you. If you are more a DBA or show me the SQL type then you can just type SQL directly.
Some advantages of TopLink would be:
-The range of SQL generated by TopLink is limited, but if you hard code complex SQL into your service you need to maintain it.
-TopLink can generate at runtime the correct SQL for a given database, making switching from say DB2 to Oracle easy.
-The merge operation will compare the input XML to the columns on the database and update only what has changed. It can also do a sparse merge. If only 4 columns in the XML were set, only those 4 columns in the database will be updated.
-For inbound polling the strategy used (LogicalDelete, Sequencing Table, etc) is a configuration property and then at runtime multiple SQL statements are generated. The SQL also takes advantage of advanced syntax like the Oracle-only FOR UPDATE SKIP LOCKED, writing it all yourself may be tedious and error prone.
-The main benefit of TopLink is when you go beyond thinking about a single table. If you import multiple related tables at once, TopLink will generate the SQL to select from and maintain multiple tables, establish a commit order, and generate a hierarchical XSD. With custom SQL the matching XSD is always flat. I.e. if you just need to insert an emp you could get away with custom SQL. If you need to insert a dept and emps, I would use TopLink.
-This is also when the intermediary abstraction of an object/table makes more sense, as you only need to import a complex relational schema once, then generate inserts, selects, etc.
So I hope that helps. They are each equally viable and can do something that the other can't. Where you see an overlap I would go with personal preference.
Thanks
Steve

Why use interlaced ?

We shoot with DVCpro50 at 24p.
A few questions.
1. Is there anytime that there is an advantage, or a time when you have to use field dominance ?
Interlaced footage looks like crap. Stills look horrible in an interlaced timeline - why ever use it ?
It seems I can just switch the field dominance from "lower/even" to "none" and everything looks 10 times better on computer and NTSC monitor.
2. Is there anytime that there is a disadvantage to removing the pulldown and editing in 24fps. It looks 10 times better without the screwd up "B/C & C/D" frames if you leave it in and edit at 29.97fps.
3. is there any advantage or quality enhancement by removing the pulldown in "Shake" rather than letting FCP do it while capturing. And after removing, should your sequence timeline be set to 24fps or 23.98fps and why ?
4. Have G5, OSX 10.4.8, AJA IO hooked up to NTSC monitor, and can't view 24fps timeline on external NTSC monitor - only frames when parked - is that because these monitors will only accept 29.97 field dominated footage ?

Fist off - thanks for the help on part 4.
I know how TV works and why NTSC was invented over a half century ago.
Now that I can monitor on the external I will always edit in 24. I'm only the editor - they shoot with a SPX900 in 24p - if you don't remove the pulldown, frames 3 & 4 out of the 5 frame cycle combined with the interlacing gives really bad results. So out of curiosity I switched the sequence dominance setting from "lower/even" to "none" - at this point is ii still treated as interlaced or if it is set to "none" is it now progressive, like when you are editing in 24 and the field dominance window is greyed out. I would think that this would look jittery on a TV because the field order isn't right - but it doesn't - I can make DVD, VHS(not sure why), and monitor and the only difference is that the stills look incredibly better - there's no banding and stair stepping on the shoulders- on either the computer monitor or the NTSC monitor. And with it set to "lower/even" the bigger the computer or TV screen the worse it looks - but with it set to "none" the stills just get softer as you view them on bigger screens as if the right amount of gaussian blur was being added automatically - Isn't that wht you want ?
So that was why I ask "why use interlace" if you have a choice?
I'm not trying to be cool - these are ligitimate questions. I consider this doing my homework - isn't that what forums are for - I help people with answers all of the time.
As for part 3 - Does "standard pulldown" refer to going back & forth between 24fps (film) and 29.97 (video) and "advanced pulldown" from 23.98 to 29.97 ?
Are all of these modern video cameras actually shooting at 23.98 ?

Hi Frank,
In the example, the "{cache-name}" is supposed to be replaced by the database's table or view name that will be queried for the data to be cached. It's purpose is demonstrate how to pass parameters to the class constructor.

Why use layer masks and adjustment layers?

I've been using PSE and CS successfully for years.
One thing I have never understood is: why use layer masks and adjustment layers, instead of simply creating a copy of the subject layer (the one I want to make changes to) and experimenting with that? It's quick (Ctrl-J), I can do it as many times as I want, I'm not affecting my Background layer. If I like the changes, I can keep them. I can switch the copy on and off to compare with the Background layer. I can do any type of blend or combination I desire. I can insert Gradient layer(s), select any part of the copy and (Ctrl-J) create a new layer containing only the selected part. I can adjust size, rotate, do anything.
It almost seems that "layer mask" and "adjustment layer" are mainly another layer of terminology; can anyone explain (preferably in 50 words or less) how they are intrinsically different from or superior to working with copies of the Background layer? What can be done with them that can't be done simply using copies of the Background layer?

Here's a very basic example of the advantage of using a layer mask.
I have this picture of a sunflower and I want to convert the background to black & white, leaving just the flower in color. I duplicated the Background layer, converted it to B&W and proceeded to use the Eraser to uncover the flower color. But I made a mistake and erased outside the flower. There is no way to correct this other than deleting the layer and starting again.
Now let's use a layer mask on the B&W layer. Set the Foreground/Background colors to the defaults black/white. Using the Brush tool paint on the mask with black to reveal the color. Here I painted too far, revealing a green leaf in the background. No need to start over. Simply switch to white and paint the excess to convert back to the B&W.
Tip: while painting you can type "X" to toggle between black and white.
You could also select the flower using the various selection tools and then fill the selection with black. If it turns out the selection was not 100% accurate you can then fine-tune the result by painting on the mask with black or white as necessary.

TS2771 how can i get my speaker to my iPod touch 5th generation to work i cant hear with without using the ear phone's

How can I get my speaker fixed I cant hear only when I use my ear phones

- Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so.
Try the following to rule out a software problem
- Reset the iPod. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup
- Restore to factory settings/new iPod.
- Make an appointment at the Genius Bar of an Apple store. Seems you have a bad headphone jack.
Apple Retail Store - Genius Bar
If not under warranty or the iPod has been abused, Apple will exchange your iPod for a refurbished one for this price. They do not fix yours.

Can you use iPhone ear buds microphone with your MacBook Air?

If you use your ear buds to listen to your Facetime conversations, are also using the microphone on them to talk?

Yes you can. Any headset compatible with the iPhone works just fine for full duplex conversation on a MacBook Air of current design. The microphone and earphones are simultaneously active.

Why using workarea for internal table is better in performance

Please tell me
why using workarea for internal table is better in performance

Hi Vineet ,
Why would we choose to use an internal table without a header line when it is easier to code one with a header line?
it has following reason.
1)Separate Internal Table Work Area:
The work area (staging area) defined for the internal table is not limited to use with just one internal table.
take ex-
Suppose you want two internal tables for EMPLOYEE one to contain all records and one to contain only those records where country = USA. You could create both of these internal tables without header lines and use only one work area to load data into both of them. You would append all records from the work area into the first internal table. You would conditionally append the USA records from the same work area into the second internal table.
2) Performance Issues: Using an internal table without a header line is more efficient than one with a header line
3) Nested Internal Tables: If you want to include an internal table within a structure or another internal table, you must use one without a header line.
If this one is helpful ,then rewards me
Regards
Shambhu

No sound after using the ear phones

i was watching you tube video using the ear phone. when to to do something cam back no sound. with or without ear phones. i am not very technial so n idea what to do as i am in Fiji on holidays.

If there is a red light in the audio output port, insert the earphone plug a few time to see if you can trip the internal switch. If that fails, insert a cocktail stirrer or the like and jiggle inside in order to trip the switch. If that fails, go to a repair facility and have them trip the switch.
Ciao.

Why use go:title etc...

I've just seen this in the meta data of a website:
<meta property="og:title" content="foobar...
There's loads of them… go:description… go:audio… go:keywords… and so on
Apparently it's to do with open graph and Facebook which I don't fully understand, but why use it and what are the advantages? I've googled it, but I'm finding little ore than what I already mentioned. Just wondering if anybody here knew a little more detail than the info I've found.
Thanks.

From this page - Facebook Content Sharing Best Practices
I read:
Use proper Open Graph tags
Open Graph tags are included in your page’s HTML and allow the Facebook Crawler to generate previews when your content is shared on Facebook.
We give examples below, but the basic Open Graph tags you should implement are:
og:title – The title of your article, excluding any branding.
og:site_name - The name of your website. Not the URL, but the name. (i.e. "IMDb" not "imdb.com".)
og:url – This URL serves as the unique identifier for your post. It should match your canonical URL used for SEO, and it should not include any session variables, user identifying parameters, or counters. If you use this improperly, likes and shares will not be aggregated for this URL and will be spread across all of the variations of the URL.
og:description – A detailed description of the piece of content, usually between 2 and 4 sentences. This tag is technically optional, but can improve the rate at which links are read and shared.
etc.

Why use synchronized to decorate an object which its type is Vector

Hello,guys.
Recently,I readed the source code of java.util.Observable.Unfortunately,I encounted some problems。In the source code ,there is an object named obs.Its type is Vector. As we all know,Vector is thread-safe.why use synchronized in below code?
    public synchronized void deleteObservers() {
     obs.removeAllElements();
    }thanks.

My " NewBie" Definition of Thread Safe :Is of no interest. It already has a definition and that isn't it.I wanted to make clear what my definition is.
The [JLS DEF FOR COLLECTION|http://java.sun.com/j2se/1.4.2/docs/api/java/util/Collections.html] says:
That is the Javadoc for Collections actually, nothing to do with the JLS or Collection.They are authoritative links for Java Language and the discussion in hand, not Fantasies of Lucy Aunty.
So,how do we draw any inference(s) here?Yes, that you have selectively quoted the Javadoc, which goes on to talk about how you have to use it when iterating.Still not answering my question,Sir.
ejp,you seem to have knowledge but you don't have the attitude to forward the same to others or bear what others say,even when initiative has been taken by others to put forward a problem.

Why use KeyExtractor here? How about remove it?

Please see the following script:
setResults = cache.entrySet(new AndFilter(
new LikeFilter(new KeyExtractor("getLastName"), "S%",
(char) 0, false),
new EqualsFilter("getHomeAddress.getState", "MA")));Why use KeyExtractor here? How about remove it and make it like:
setResults = cache.entrySet(new AndFilter(
new LikeFilter("getLastName"), "S%"),
new EqualsFilter("getHomeAddress.getState", "MA")));Is this scrip right?
Edited by: jetq on Oct 23, 2009 2:08 PM

I Googled for KeyExtractor and the likeliest-looking thing was javadocs for com.tangosol.util.extractor.KeyExtractor on an Oracle site.
Why don't you check around the Oracle developer site for a forum specifically about whatever product this is?
